The point is that a bid placed in the FIRST second of an eBay auction can beat a bid placed in the LAST second, IF IT'S FOR A HIGHER AMOUNT. If you lost because you would have paid more but didn't get the chance, you're doing it wrong. This program, once installed, will allow you to block all bids but yours on ebay, allowing you to win auctions for dirt cheap! Snipe auctions!
To stop a particular member from being able to bid on or buy your items:
Go to the Block bidders or buyers from your listings - opens in new window or tab page.
Enter their username – You can add up to 5,000 usernames.
Select Submit.
Tip You can restore a past blocked bidder/buyer list by selecting Restore list.
If you want to unblock someone at a later date:
Go to the Block bidders or buyers from your listings - opens in new window or tab page.
Delete the username of the member from the text box.
Select Submit.
You can also choose to block buyers based on specific criteria. For example, buyers living in a country you aren't willing to ship to or buyers with unpaid items cases. Here's how:
Go to Selling preferences - opens in new window or tab in My eBay.
